UNITED STATES KELLY I. FRANKLIN, OF TILLAIVIOOK, OREGON.

SAWMILL TRACK ADJUSTER.

Application led November 12, 1923.

To all whom it may concern Be it known that I, KELLY I. FRANKLIN, acitizen of the United States, residing at Tillamook, in the county ofTillamook and State of Oregon, have invented certain new and usefulImprovements in Sawmill Track Adjusters; and I do declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

In mounting saw mill carriages, two parallel rails are employed, saidrails being supported upon a pair of sills. One of these rails isusually flat to co-operate with carriage rollers having transverselystraight treads, while the other rail is formed with a longitudinal ribor the like for reception in grooves of other carriage rollers, so thatthe rib and the grooved rollers co-operate in guiding the travel of thecarriage. It often happens however that the ribbed rail, from one causeor another, gets materially out of line, which causes the mill toproduce poor work. It is the object of my invention, to provide simpleand inexpensive means whereby the ribbed rail may be laterally adjustedupon its supporting sill, so that it may at all times be kept in properalinement, regardless of irregularities in the sill.

lVth the foregoing in view, the invention resides in the novel subjectmatter hereinafter described and claimed, the description beingsupplemented by the accompanying drawing.

Figure l is a transverse sectional view through the ribbed track railand its supporting sill, showing in elevation one of the adjustersassociated with said track and sill.

Fig 2 is a View similar to Fig. 1 but cut in a different plane.

Figure 3 is a fragmentary plan view, and the plane upon which Fig. 2 iscut, is indicated by the line 2 2 of this Figure 3.

Figure t is a fragmentary side elevation of the ribbed track and itssupporting sill, showing the association of one of the adjusterstherewith.

Figure 5 is a vertical sectional view on line 5 5 of Fig. 2.

Figure 6 is a side elevation of the trackadjusting block and itsoppositely extending threaded studs.

In the drawing above briefly described, the numeral l designates asupporting sill for Serial No. 674,272.

a ribbed track rail 2, but instead of spiking or bolting the rail to thesill in the usual manner, I connect the two by means of the improvedadjusters. In the preferred form of construction, each adjuster includesan elongated metal plate 3 inset in the upper side of the sill 1 andextending transversely thereof, said plate being secured in place byspikes, lag-screws or the like 4l. The plate 3 is provided with a slot 5which extends longitudinally of said plate but transversely of the silll, said slot slidably receiving a substantially rectangular block 6having a seat or recess 7 for receiving and holding the base of thetrack rail 2. rlhe block 6 is provided with oppositely extendingthreaded studs 8, and the sill l is transversely grooved as indicated at9, to slidably receive said block and studs.

The ends of the plate 3 are provided with downwardly extending abutments10 which are apertured to receive the studs 8, one abutment beingpreferably formed with an opening 11 of circular form, while the otheris provided with a slot 12 opening through its lower end, these shapingsfor the apertures, being employed in order that the de-.

vice may be easily assembled. Nuts 13 are threaded on the studs 8 inContact with the outer sides of the abutments 10 and it will be seenthat by loosening one nut and tightn ening the other, the rail 2 may beadjusted laterally to the necessary extent. Tightening of the irstloosened nut, will then tightly clamp the rail in place. It is of courseunn derstood that the adjusters are`used at suitably spaced pointsthroughout the length of the track rail 2 and it will be seen that byproperly setting said adjusters, the rail may be kept in accuratealinement, to permit the production of best results by the mill or othermachine upon which the adjuster-s are used. As excellent results areobtainable from the details disclosed, they are preferably followed, butwithin the scope of the invention as claimed, numerous minor changes maybe made and obviously the invention is not restricted in use to sawmills, but may be employed wherever it will be of advantage.

I claim:

l. A track rail adjuster comprising a slotted plate adapted to extendacross the upper side of a sill, apertured abutments extendingdownwardly from the ends of said plate for contact with the verticalsides of the Sill, a blek SIiQlebIy received 11.1 the Slot 0f said plateand having provision for holding. a rail, studs extending oppostelyylronfrsid block through the aperture of said abutments, land nutsthreaded adjustably on said studs in Contact with the outer sides of sgdabutments. Y

2. In combination 'with a sill haying a transverse groove in its upperside, e pleteA extending across the upper. side ofl sill ple-Ee 11.1engagement with the edges thereof and; beingy pertured opposite'theiendsof said groove, al block slidable in said groove and sid slot andprovided with means to holdin ril, studs projecting from the oppositeends of seid block endpassing through the apertures in said abutments,and nuts threaded on Sigrid Studs Vand engaging the outer ysidesoi saidabutments.
